LyX full changelog

Here are some highlights:
There have been a number of updates to LyX's interface with compute algebra systems.
LyX now (again) has a function (error-next) and a menu entry (Navigate > Next Error) to quickly jump to the next compilation error; also, a function (errors-show) and a menu entry (Document > Processing Errors) to (re)open the dialog that lists compilation errors after it has been closed.
Another important fix concerns the generation of previews. In certain cases, LaTeX adds a temporary page at the end, and this confuses our python script that generates previews.

We are proud to announce the third maintenance release in the LyX 2.4.x series. This is mostly a bug-fixing release. Most of the bugs are minor, but there was one significant one (13118) concerning the loading order of the fancyhdr package that was causing errors in page layout. In terms of updates, the most significant are that it is not possible to insert cross-references from the outliner, even to sections that have not yet been given a label. In that case, the label is automatically created. There has also been a major update to the Swedish localization.

This is almost entirely a bug-fixing release, with no significant new features. However, some crashes have been fixed, and we have made some significant improvements to display speed, which will be especially noticeable on older or slower systems.
There has been a change (as of 2.4.0) in how the option to use vertical space between paragraphs is handled. Previously, LyX simply modified parskip and parindent, but this caused various problems (see bug #4796). Now, we use the parskip package. As a result, however, and to ensure there are no changes to old documents, when LyX files from 2.3.x and earlier are converted to the new format, if they were set to use vertical space between paragraphs, the lyx2lyx conversion routine adds
% Added by lyx2lyx
setlength{parskip}{smallskipamount}
setlength{parindent}{0pt}
to the preamble and, within LyX itself, resets the text layout to use indentation (so we do not issue the new code for vertical spacing). The net effect is that PDFs generated with LaTeX (etc) look right, but in LyX itself indentation is used.
This will happen with any document created with 2.3.x or older. It can also happen with documents created from templates created with 2.3.x or older, and even with new documents, if you had previously set them to use, by default, vertical space. Templates are just LyX files saved in the templates/ folder, and the 'defaults' are simply saved in a template file, defaults.lyx. Hence, if you want the new behavior, or just want the LyX document to look `right', then you will need to make two changes to the document or template: Remove what lyx2lyx added, and then set Paragraph Separation to Vertical Space.

This update fixes two problems.
The first is that the inclusion of TeX files as child documents was unintentionally broken by the new code that allows for the creation of new files from the child document dialog. The second is that there was some odd behavior of menus under Gnome Wayland, at least on Fedora, due to how window positions were stored between sessions.
Otherwise, this version is the same as LyX 2.3.6, and users who do not experience these problems need not upgrade.

We are pleased to announce the release of LyX 2.3.6. This is the sixth maintenance release in the 2.3.x series. It is the result of on-going efforts to make our stable version more reliable and more stable. Most of the changes are fairly minor, fixes of smallish bugs, but a couple crashes have been fixed, as well.
One oft-requested feature (going back 13 years) is the ability to create new child documents from within the 'include file' dialog. This is now possible. Another equally old bug that has been fixed is that pasting table content outside a table no longer pastes tab characters.
With 2.3.6, we also release an updated version of the Windows installer. (It has been available for previous versions for testing.) Perhaps the most significant change is that LyX is now available as a 64 bit Windows application.

This is an emergency release to fix bug number 11889, which reverse quoation marks in some cases when hyperref is enabled. It is otherwise unchanged from the release of LyX 2.3.5.

LyX 2.3.5 is the result of on-going efforts to make our stable version more reliable and more stable. Most of the changes are incremental, but quite a few important bugs have now been fixed. One important change is that Inkscape 1.0 is now supported: It will be detected and configured automatically. Users of previous versions have recently reported configuration failures when Inkscape 1.0 is installed, leading to an incomplete (and all but unusable) installation of LyX. This should also be fixed.
